>             Project: Hive
>          Issue Type: Improvement
>          Components: Query Processor
>    Affects Versions: 0.9.1, 0.10.0
>            Reporter: Keegan Mosley
>            Priority: Minor
>         Attachments: HIVE-3236.1.patch.txt
> When using "CREATE TABLE x AS SELECT ..." where the select joins tables with 
> hundreds of columns it is not a simple task to resolve duplicate column name 
> exceptions (particularly with self-joins). The user must either manually 
> specify aliases for all duplicate columns (potentially hundreds) or write a 
> script to generate the data set in a separate select query, then create the 
> table and load the data in.
> There should be some conf flag that would allow queries like
> "create table joined as select one.\*, two.\* from mytable one join mytable 
> two on (one.duplicate_field = two.duplicate_field1);"
> to create a table with columns one_duplicate_field and two_duplicate_field.
